1. A light irradiation device comprising:
a circuit unit comprising
a plurality of tube holding portions, each of the tube holding portions being in a generally co-planar relationship with the other tube holding portions and each one of the tube holding portions having a plurality of fluid tubes extending there through,
an inlet tube fluidly connected to an inlet end of each fluid tube of the plurality of fluid tubes,
an outlet tube fluidly connected to an outlet end of each fluid tube of the plurality of fluid tubes, and
an attachment assist portion connected to the tube holding portions and supporting the tube holding portions in said generally co-planar relationship,
and
an irradiation unit comprising
a plurality of arrangement portions, each of the arrangement portions being in a generally co-planar relationship with the other arrangement portions and each arrangement portion being separated from an adjacent arrangement portion by a groove, and
a plurality of LED lamps which are mounted in each of the arrangement portions facing one of the grooves formed by adjacent arrangement portions and which irradiate the blood or the blood component flowing through the plurality of tubes with light so as to inactivate a virus included in the blood or the blood component,
wherein the circuit unit may be coupled to the irradiation unit by inserting the tube holding portions into the grooves of the irradiation unit using the attachment assist portion.
